Fig. 1 Tools for removing and installing drive pinion nut
A - 32 mm wrench socket

Fig. 2 Removing drive pinion nut
- Install 3304 retainer using two hex bolts M8 x 30.
- When nut is removed, final drive must be supported (e.g. using
VAG1359/2 universal mount together with VAG1383A transmission
hoist).

Note:
If the specified friction torque is surpassed, replace spacer sleeve and
repeat adjustment! Any spacer sleeve that has been pressed together too
far one time must be replaced. Fig. 11 Tightening drive pinion nut and adjusting friction torque
- Install 3304 retainer using two hex bolts M8 x 30.
- When tightening nut, support final drive (e.g. using VAG1359/2
universal mount with VAG1383A transmission hoist).
- Always replace drive pinion nut.
- Tighten nut for drive pinion until no more drive pinion backlash is
present.
- Tighten further until specified friction torque is attained; while tightening
measure friction torque multiple times Fig. 12
